Recording Mid-Sides Recording on a Zoom H2n

I've got a Zoom H2n portable digital recorder which is really convenient and surprisingly good for capturing live sound.

I think it has four separate condenser microphones built in and you can choose the way they are recorded, from:
  • XY (two cardiod microphones angled at 90 degrees)
  • 2 channel
  • 4 channel
  • MS (mid-sides)
Up to now I have always used the XY and taken the resulting recording directly as a stereo file. When I did this most recently on our saxophone quintet I found that the saxes on the outside (far left and far right) seemed louder than the instruments in between.

Now I am thinking of experimenting with the Mid-Sides recording set up. It produces just two audio channels, one from the forward-facing mid mic and one from the left and right -facing sides mic. It seems that you have to duplicate and then invert the sides-mic channel to get separate left and right channels, each panned hard over. You can then play around with the relative volumes of the mid and the sides channels to vary the stereo width. The MS technique is introduced in this video.


Do any of you use your Zoom devices in this way or use Mid-Sides on other devices ?

I use mid side quite often but don’t know the zoom.

It will work well for rebalancing and assuming the matrix cleverness is all done within the device then you will control the balance by widening or narrowing the stereo image.

But if it outputs unencoded then it would be a different kettle of fish and more complex. The side channel will need splitting into two and one side phase inverted then remixed in with the mid (mono)

I bet you wish you hadn’t asked.

Thanks @Pete Thomas . The Zoom website has VST Plug-Ins for Mid-Side Mic Decoders. Zoom H2n Handy Recorder

I think I need to do some experimentation, comparing the results of MS with XY and doing the MS decoding manually or with some automation. I use Audacity as my DAW and am not familiar with VST Plug-Ins.
